Dementia
Dementia is a mental health condition characterized by cognitive decline in
thinking, reasoning, remembering as well as the behavioral abilities to an extent that an
individual may not carry out daily life and activities (Alzheimir’s Association). The
different types of dementia include Alzheimer’s, lewy body, perkinsons, vascular,
frontotemporal, wernicke-korsakoff, creutzfeldt-jakob and mixed dementia. Dementia
extends in seriousness from the mildest stage (National Institute on Aging 2018).
Diagnosis Criteria
Doctors diagnose dementia based on medical history, physical examination,
behavior associated with an individual’s day to day functions, laboratory tests as well as
distinguishable changes in thinking (Dubois et al. 2014). Alzheimir’s Association argues
that diagnosis criteria should be focused on the three stages.
Signs and Symptoms
The signs and symptoms of dementia greatly vary depending on the type of
dementia as well as the stage. They may slowly start out and gradually worsen.
However, the most common signs and symptoms that cut across all types of dementia
include memory loss, difficulty in communicating, finding words, solving problems,
handling complex tasks as well as difficulty in planning and organizing (Mayo Clinic
2017). Changes in personality, depression, anxiety, agitation, hallucinations and
inappropriate behaviors are also signs of dementia. Additionally, difficulty with motor
functions and coordination as well as confusion and disorientation are also signs and
symptoms of dementia (Singh-Manoux et al. 2017).
Epidemiology (Causation, Prevalence, Co-Morbidity, Prognosis)
Several different illnesses can cause dementia. A considerable lot of these
diseases are related to an irregular development of proteins in the brain (Alzheimer's
Association 2017). This development causes nerve cells to work less well and
eventually die. As the nerve cells die, diverse regions of the mind shrink. Genetic
mutation may also cause some nerve cells in the brain and the spinal cord to waste

away. According Wood (2018), gout is associated with a 17 to 20 percent higher risk of
dementia in the elderly. This is because its treatment involves lowering the use of uric
acid which is believed to protect the brain. Dementia may also be as a result of
repetitive head trauma (Mayo Clinic 2017). This damages the vessels which supply
blood to the brain as well as degeneration of nerve cells.
According to National Health Service (2018), 1 person in every 130 people
suffered from dementia. This indicates a progressive increase by 0.29% from the
previous recorded prevalence in 2017. This research found out that 69.7% of people
who are over 65 years old have a coded dementia diagnosis recorded. In addition to
that, dementia diagnosis is 18% higher in people from the black ethnic group as
compared to Asian and white people (Pham et al. 2018). However, this varies among
men and women. Nonetheless, it is also important to note that dementia occurs to
people of all ages (Van De Vorst et al. 2016).
In most cases, people with dementia are always living with undiagnosed co-
morbidities. The two most successive comorbidities both for people with dementia are
hypertension and diabetes (Prince et al. 2016). The comorbidities which are
fundamentally connected with dementia are Parkinson's ailment, congestive heart
failure, cerebrovascular ailment, iron deficiency, cardiovascular arrhythmia, perpetual
skin ulcers, osteoporosis, thyroid infection, retinal issue, prostatic hypertrophy, sleep
deprivation and tension and mental issues (Poblador-Plou et al. 2014). These
cormobidities may result to prolonged hospital stays and may accelerate the
progression towards a condition of psychological and useful debilitation that is as an
outcome of under-diagnosis and under-treatment of dementia.
The prognosis of dementia varies from one type to another. However, it is
important to note that they all occur from early stages to the late stages (Perani et al.
2016). The prognosis of dementia greatly varies from the amount of damage caused,
health and the age of an individual. According to Pujades-Rodriguez et al. (2018), the
average life expectancy of a person suffering from dementia ranges from 8 to 10 years
from the time of diagnosis even though others may live up to 20 years.
